Hey everyone!
So I have an issue. I have a 2004 grand prix, I am the only owner and have done 99 percent of the repairs myself and it has 300,000 miles but drives unbelievable and drives brand new. I am a DIY guy and have replaced tons of stuff on this car myself as simple as brakes and as hard as the rack.
The problem:
I am leaking coolant, under the car near the passenger side. I have recently had the high pressure power steering hose replaced by a mechanic because I didn't have time and needed it done quick, the coolant is leaking somewhere near that area where it attached to the power steering pump. I have checked the water pump with no leaks and its new with about 5k miles on it. Radiator is not leaking, all the big rubber hoses that the radiator sends and receives coolant are not leaking. The hard plastic elbow's are not leaking. The hose connecting the reservoir is not leaking. Radiator is not leaking. The hoses that go into the firewall are not leaking (both). No white smoke from the mufflers and no foamy oil. I recently had a pressure test done on the motor, and the gaskets are good.
Heater does not blow out very hot air, it is luke warm at best. Is my heater core cracked? Water leaking to the bottom of the car and draining thru a hole of some sort on the under-body?
I am going insane, and just came inside, with the temp. getting warmer, I need to figure this out. I do have other cars to drive but love this one as my daily driver.
Love it if I am over-looking something quick and easy, I am thinking the heater core or maybe the mechanic who replaced the power steering hose knocked something loose. It happened right around the same time that was repaired.
